Convert btu (it)/hour/sq. foot/°f to kilocalorie (it)/hour/sq. metre/°c
Btu (IT)/Hour/Sq. Foot/°F
The British thermal unit per hour per square foot per degree Fahrenheit (Btu/(h·ft²·°F)) equals approximately 5.678 W/(m²·K). It is the standard imperial unit for heat transfer coefficient (U-value) in North American HVAC, building codes, and heat exchanger design and is related to the R-value of insulation.
Kilocalorie (IT)/Hour/Sq. Metre/°C
The kilocalorie (IT) per hour per square metre per degree Celsius (kcal/(h·m²·°C)) equals approximately 1.163 W/(m²·K). It is widely used in older European and Asian engineering standards for heat exchangers, radiators, and building thermal analysis where metric-caloric units are preferred.
